I just bought a nice used ESAB 260 multimaster, with a spool gun and tig torch . I was wondering about which gas to get for the mig side. I know 75/25 is the standard gas, however this machine has got the guts to do spray. Spraying is something I know nearly nothing about as I have never had the opportunity to use a machine capable of spraying. So my question is, Will 75/25 spray, or do I need 85/15? If I do 85/15 will it do short arc? If at all possible I would like to stay with one gas for mild steel. I don't want to fill up a single stall garage with tanks: oxy, acet, 100% Argon for the alu and tig, 75/25, and 85/15. Thanks everyone in advance, I'll be posting alot in the near future, I  have alot of projects planned.Rick
Reply:I use 90/10 for short circuiting and spray. it works good enough for me on low settings. produces a very nice spray.only thing worse than an ugly woman is an ugly weld
Reply:Ive used 90/10 on short circuit plenty and it does a nice job, seems like a little less spatter than C25.  Im sure it works just as well on spray also.Have we all gone mad?

Reply:Very nice welds. Thanks to all of you for the replys. Going to pick up my new to me welder tommorow. It will probably take me a couple days to get it set up, and acquire my gases and fillers, and change some electric around. I'll practice with it and see how it does, and post up my pics. I'll give the 90/10 a try if my LWS has it. Thanks again folks.
